Fluid Mechanics - Problems and Solutions

Author | Bahodir Ahmedov Complete solutions of the following three problems: 1. A water flows through a horizontal tube of varying cross section. In the first segment the cross section is 15 cm2, the flow speed is 2 m/s, and the pressure is 120 kPa. In the narrower segment the cross section is 5 cm2. What is the flow speed in the narrower segment? 2. What is the pressure in a lake at see level at a depth of 10 m? 3. A cylindrical tank of 4 m diameter open on the top has a hole of 1 cm diameter 15 m below its free water surface. What is the speed of water flowing out through the hole?
